Comparing Sandwich Wall Panel Shear Connector Testing Methodologies, Parker S. Syndergaard
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Precast concrete sandwich wall panels (PCSWPs) have been used in the precast industry for decades due to their durability, rapid construction, and thermal efficiency. Shear connectors are used to connect the two wythes of concrete to allow composite action of the system. In order to design concrete sandwich panel systems to act compositely, the engineer must obtain design values from a connector manufacturer, often times making engineers uncomfortable. Shear connectors are typically proprietary, and are required to first have design values validated through destructive testing. The method in which connectors are validated often times varies by each company. This project …

Performance Of Transverse Post-Tensioned Joints Subjected To Negative Bending And Shear Stresses On Full Scale, Full Depth, Precast Concrete Bridge Deck System, Kayde Steven Roberts

Accelerated bridge construction has quickly become the preferred method for the Utah Department of Transportation (UDOT) as well as many other DOT’s across the United States. This type of construction requires the use of full depth precast panels for the construction of the bridge deck. The segmented deck panels produce transverse joints between panels and have come to be known as the weakest portion of the deck. Cracking often occurs at these joints and is reflected through the deck overlay where water accesses and begins corrosion of the reinforcement and superstructure below. For this reason post-tensioning of the deck panels …
